Abstract

The invention is based on the idea that in an intelligent network the order of execution of service programs at one point during the call, such as the detection point, is defined, and the service programs are contacted in this order until instructions are received to leave the point or release the call. The order of execution is defined by dealing with one category of service-related detection points after another, and within each category with a control relationship the order of execution is defined by a priority set for service programs.

Description

Method that business in the control intelligent network is carried out and the exchange point in the intelligent network
The business that the present invention relates in the intelligent network is carried out.
Developing rapidly of field of telecommunications makes the operator provide many dissimilar business to become possibility to the user.Such one provides the network architecture of higher level service to be known as intelligent network, it is generally used be abbreviated as IN.This type of professional example is a virtual private network, and short codes is used in its permission between special net user, and private number, and at this, intelligent network carries out route again to the calling that private number is carried out in the mode of user's control.By using the IN business such as mobile radio communication and the diverse network that is connected to the fixed network on the IN.
The physical structure of intelligent network illustrates in accompanying drawing 1, and at there, physical entity is expressed as rectangle or cylinder and the functional entity that is arranged in them is represented as ellipse.Owing in explanation of the present invention, will carry out reference subsequently, so following this structure of describing briefly to the intelligent network environment.Q.121X interested reader for example can advise or obtain the more understood in detail of intelligent network from ITUT from the AIN suggestion of Bellcore.ETS 300 374-1 CorelNAP clauses will be used in explanation of the present invention and its background note, but the present invention can also use in the intelligent network of realizing according to other intelligent network standards.
Subscriber equipment SE for example can be a telephone set, travelling carriage, and computer or facsimile machine, it is directly connected to Service Switching Point or is directly connected to Network Access Point NAP.The service switching point provides the access of network and is concerned about the dial feature that all are essential to the user.SSP can also detect the demand of intelligent network business request.In the function clause, SSP comprises call manager, route and professional dial feature.
The service control point (SCP) comprises service logic program SLP, and it is used to produce intelligent network business.Below, also will use " business procedure " as the shortening form of " service logic program ".Service data point SDP is a database that comprises these data of relevant user and intelligent network, and the SCP business procedure uses this database to be used to produce personalized business.SCP can directly use the SDP business by a signaling or data network.
Ip intelligent peripherals IP provides special function, for example notice, and speech and a plurality of dialing sign and so on.
Signaling network as shown in FIG. is the network according to Signaling System 7(SS-7) (SS7), is a known signaling system of describing in the specification (Melbourne 1988) of the No.7 signaling system of CCITT (present ITU-T).
Call control agent function (CCAF) guarantees that terminal use (user) can access network.The access of IN business realizes by existing digital switch is increased.This point is undertaken by using Basic Call State Module BCSM, and it has been described call treatment at different levels and has comprised in order to start those points or the test point DP that intelligent network business can interrupt call be handled.At these test point places, the service logic entity of intelligent network can be in a kind of interaction relationship with basic call and connection management function.In switch, call setting is divided into two parts: call setting in the originating terminal part and the call setting in terminal portion.As explanation roughly, the call treatment in the originating terminal part is relevant with calling subscriber's business, and the call treatment in terminal portion is relevant with called subscriber's business.The corresponding states pattern is originating terminal Basic Call State Module (O-BCSM) and terminal Basic Call State Module (T-BCSM).BCSM is the senior state automator narration (high-level state automaton description) that is provided with and keeps needed those CCF of connection (CCF) between the user.Under the help of Service Switching Function (SSF), function is added to this state model (CCF in the cf. accompanying drawing 1 and SSF part are overlapping) so that make it can determine ask intelligent network business (being the IN business) when.When the IN business has been requested, comprise the Service Control Function of the service logic of intelligent network, carry out and professional relevant processing (in call setup).Therefore, Service Switching Function SSF is connected to service control function SCF to CCF CCF and allows service control function SCF controlling call controlled function CCF.
Intelligent network business is realized in so a kind of mode: relevant for meeting with the related service test point, instruction is inquired to the service control point (SCP) in the service switching point under the help of the message of passing through SSP/SCP interface relaying.These message are known as operation (operations) in the intelligent network term.SCF for example can ask SSF/CCF to carry out some calling or linkage function, for example charges or routing operations and so on.SCF can also transmit a request to service data function (SDF), and it provides the visit to the network data of related service data and intelligent network.Therefore SCF for example can ask SDF to fetch about some professional data or ask it to upgrade this data.
Provide interface to those network equipments to add to be included in above-mentioned function in the interaction with the user by the resource function SRF that becomes privileged.Example is exactly to user's the message and the collection of subscriber dialing.
Be brief description below by the task of IN business functional entity as shown in Figure 1.CCAF receives the service request that the calling party makes, and this picks up receiver by the calling party and/or dials some number series and carry out in typical case.CCAF continues that this service request is relayed to CCF/SSF and is used for handling.CCF does not have business datum, discerns those test points that can carry out the SCP visit but it is programmed.CCF interrupts call setting a little while and provides the Service Switching Function SSF data of relevant test point of meeting (relevant call setting level).The task of SSF is to be used for explaining by making of settling the standard in advance whether this operation is a service request relevant with intelligent network business.If this situation, then SSF sends a standardization IN service request to SCF, comprises the data relevant with this calling.SCF receives this request and it is decoded.It is cooperated with SSF/CCF, SRF and SDF so that produce the business asked for the terminal use then.
Just as set forth above, when SSF business when SCF sends standard I N service request is activated.Service request can send during some level of calling out.Fig. 2 has illustrated some basic operations in the up-to-date function of the intelligent network at test point place.21 SSP of place send initial DP (InitialDP) service request to SCP at point, include the master data of closing the calling that starts intelligent network business.So then be the help of the test point among the SSP.Send request report BCSM incident (RequestReportBCSMEvent) operation at point 22 SCP of place to SSP, tell SSP which test point it should report to SCP.Next, at point 23 places, SCP sends charging and/or the operation that interacts in typical case, such as using (ApplyCharging) (for example request of charging report) of charging or broadcast notice (Play Announcement) (giving notice of user).At point 24 places, SCP sends route instruction to SSP, for example connects (routing calls to a new digit) or continues (making call setting and identical data continuation).When it was consistent with the test point of SCP reservation, then at point 26 places, SSP sent an event report BCSM (EventReportBCSM) operation to SCP.
The test point of determining in the intelligent network structure is the principal organ that is used to report variety of event.Incident 21-24 among aforesaid Fig. 2 relates to the test point that is called as trigger detection point (TDP).SSP can be just carries out initial inquiry relevant for the business of the SCP of the test point of relevant TDP business.Therefore, the professional beginning of the new IN of relevant TDP.Locate in so-called trigger detection point request (TDP-R), call treatment is stopped till SSP receives instruction from SCP.Therefore, between SSP and business procedure in question, form a control relation.Locate in trigger detection point notice (TDP-N), only the notice of relevant experience related service test point is sent to SCP and needn't wait for that instruction just continues call treatment from SSP.Be stored in the network with the professional relevant trigger message of various IN.For the TDP-R test point, trigger message can comprise the definition of priority, if the definition of this priority is about there are several business procedure can finish their trigger message at same test point then starts which of more than one business procedure.When only a control relation was allowed to, then startup had the business procedure of limit priority and is abandoned at the every other business procedure of that test point from the triggering business procedure.
Another type of test point is event detection point (EDP).Point 26 among Fig. 2 is illustrated in the moment of meeting the EDP test point in the process of a calling.SSP gives SCP the relevant situation report of related service test point therewith, and it sends the additional call instruction at point 28 places to SSP.Event detection point request (EDP-R) is a test point, and there, call treatment will stop till SCP sends extra-instruction at the tie point place.The help of EDP-R test point is created control relation between the particular service programming of SSP and SCP.Mean that by control relation the session between call setting side and the SCF is continuing, and SCF can provide the instruction that changes call treatment during current session.In monitor relationship, SCP can not influence the process of call treatment; It requires the SSP report variety of event relevant with this calling only.In monitor relationship, can equip event detection point notice (EDP-N).
According to the IN standard, before handling the control business procedure and business procedure that has started before the new business program, manage the monitoring traffic program everywhere at test point.Therefore, the execution sequence of various types of other related service test point is as follows in the IN network: EDP-N, TDP-N, EDP-R, TDP-R then.
According to current intelligent network standard, have only a control relation still to have several monitoring relations can relate to calling.Therefore, EDP-R problem is exactly the generation that it stops any supplementary service.When a business procedure came to keep control relation during whole calling as EDP-R by a test point of meeting at an end of calling place help, this is problem especially, so does not have intelligent network business to be activated during calling in question again.Thereby the operation of intelligent network is based on such fact: once have only a business procedure (SCP relation) thus can have control relation and can control SSP.This principle typically refers to a single point control.
If it is possible setting up multiple spot control, allow several control relation simultaneously at there, the execution sequence of business procedure will be a problem so.In the notification type of related service test point, for example EDP-N or TDP-N and so on be not because notice influences call treatment, so the execution sequence of the notice of different business is not so important.But as in TDP-R or EDP-R, when the request call processing instruction, because the execution sequence difference of service request, the result of processing is different.For example, allow at centrex service before the reproduction of call name, must start the call name business.
The objective of the invention is to control the execution of a plurality of business procedure in the intelligent network.
According to an aspect of the present invention, the method that provides the business in the control intelligent network to carry out, comprise at least one exchange point (SSP) and several business procedure (SLP), in relevant for the method for calling out, provide at exchange point (SSP) with to it and to form at least two control relation between the business procedure (SLP) of instruction, and in calling, arrange at least one particular point, wherein between exchange point (SSP) and at least two business procedure (SLP), be connected, it is characterized in that, in the method, the particular point place of calling out, determine the classification of related service test point according to the start-up mode of relationship type and this business procedure, additional a priority to business procedure and according to the execution sequence of this priority decision in each classification inside with control relation with control relation, defining the execution sequence of different business procedure and the trigger sequence of business procedure has nothing to do, and at the particular point place of calling out, by exchange point (SSP) according to the rules be linked in sequence business procedure up to order call out leave this particular point of calling till.
According to an aspect of the present invention, exchange point in the intelligent network is provided, this exchange point be configured to exchange point (SSP) and to it provide with the business procedure of calling out relevant instruction (SLP) between form at least two control relation, and configuration like this, promptly in calling, arrange at least one particular point to be connected between exchange point (SSP) and at least two business procedure (SLP) allowing, it is characterized in that exchange point is suitable for being connected this business procedure according to the execution sequence that irrespectively defines for the different business procedure and the execution sequence of business procedure till this particular point of calling is left in the order calling at the particular point place of calling out.
The present invention is based on such thought: the some place such as test point during calling out, and the execution sequence of definition business procedure, and be linked in sequence business procedure till the instruction of leaving this point or disconnecting this calling is received according to this.Define the order of execution by the classification of one after the other handling the related service test point, and in each the classification inside with control relation, by define the order of execution for the priority of business procedure setting.
According to the present invention, professional execution has such advantage: it provides the control device of carrying out a plurality of business procedure.
According to the present invention, the another one advantage of this method is: it makes the possibility that is combined into of miscellaneous service.
According to the present invention, the another one advantage of this method is: can freely send business procedure and the function of infringement combination.
Referring now to the preferred embodiment of the contact of the example shown in Fig. 3,4,5a and 5b in the accompanying drawings the present invention is described closer.

According to method of the present invention is to be independent of the method that realizes multiple spot control.A kind of method that realizes several Synchronization Control relation is such: by telling the not at the same level of operability the controllability that connects is divided into each several part, so-called controllability classification in its each inside, is preferably used single-point control.The controllability classification has been provided by some group of these instructions of being provided by business procedure, and this business procedure is acceptable to the exchange point in this controllability classification.Therefore the controllability that connects is based on subfunction.Therefore the synchronous controllability of several business procedure becomes possibility, that is to say, can provide the permission of the exchange point with the instruction that is used for call treatment is provided to several business procedure of realizing simultaneously, it provides each instruction to belong to different controllability classifications.Therefore the business procedure relevant with different controllability classifications can side by side control the operation of exchange point by the method for being determined by their controllability classifications separately as shown in Figure 3.Idle controllability classification can require to distribute to business procedure according to their controllability.Controllability be divided in state model (O-BCSM or T-BCSM) inside.The distribution of the controllability classification among the BCSM who calls out can also influence other BCSM of this calling, for example stops the initiation of services that needs identical controllability classification.The another one method that multiple spot control is provided is a test point inside control to be transferred to another one from a business procedure.
Fig. 4 represent as flow chart according to the first embodiment of the present invention.At first, for business procedure execution sequence (level 400) is set.It is favourable in the IN business information of using a new priority parameters being set, and is favourable when meeting with EDP-R at least.And can use the priority of the prior art in the IN Service Trigger Information in the method according to the invention, especially when meeting with TDP-R.Need not define execution sequence respectively at each test point.The remainder of the flow chart among Fig. 4 relates to test point or the another one fixing point in the calling.Check at first that at level 402 places EDP-N connects.If there is at least one EDP-N to give put up a notice (level 404) to business procedure in question.Execution sequence between the different business program in being connected the EDP-N classification is uncorrelated because they do not influence each other, therefore, can carry out these connections with random order in this EDP-N classification.Continue EDP-N and carry out 100 till all these connections are all processed.Next, check that at level 406 places TDP-N connects.According to prior art, estimate trigger condition for TDP-N related service program.Trigger TDP-N if carried out at least one, then start business procedure in question and to its give notice (level 408).The same with the EDP-N connection, the execution sequence in the different business program in being connected the TDP-N classification is uncorrelated.Therefore, can carry out these connections with any order in this TDP-N classification inside.Continue TDP-N and carry out 110 till all triggering connections are all processed.After that, carry out EDP-R and carry out 120.According to handling different business procedure, more favourable according to new priority parameters of the present invention by the order of some priority parameters definition.Check that at level 410 places EDP-R connects.If have the EDP-R contact to handle, then a request sent to the business procedure with limit priority at level 412 places.Call treatment is stopped till the instruction of receiving business procedure since then at level 414 places.Whether indicate this calling to proceed to certain other destination about them, for example proceed to the another one telephone number, perhaps require this calling to disconnect (level 416), instruction is estimated.In all these situations, do not have processed in the call treatment end at test point place and the EDP-R that is kept.In every other situation, the execution of EDP-R continues from level 410 according to order of the present invention.At last, when all EDP-R connections are performed and call out still at identical test point place entirely, then enter TDP-R and carry out 130.Check that at level 418 places TDP-R connects.According to prior art, estimate trigger condition for TDP-R related service program.According to the present invention, trigger business procedure according to sequential processes by some priority parameters regulation, the priority of the prior art in the IN Service Trigger Information or for example according to new priority parameters of the present invention, therefore, at first handle business procedure with limit priority, after that, handle business procedure with next limit priority, or the like.Need to carry out if there is at least one to trigger TDP-R, then startup has the business procedure of limit priority and notice is sent to its (level 420).Stop call and handle till the instruction of receiving business procedure since then at level 422 places.Equally, about they whether indicating call proceed to other position or need to call out and disconnect and (level 424) estimated in instruction.In all these situations, do not have processed in the call treatment end at test point place and the TDP-R that is kept.In every other situation, TDP-R carries out according to order of the present invention and continues from level 418.
Fig. 5 a and 5b represent some parts according to a second embodiment of the present invention.Corresponding to those levels among Fig. 4, use identical numbering with the level among the 5b at Fig. 5 a.This method is not shown in that part of among Fig. 5 a and the 5b, that is, the execution of EDP-N and EDP-R is equivalent to those parts among first embodiment.Fig. 5 a provides the TDP-N of this embodiment to carry out 110.At level 406 places, the contact first embodiment of the present invention as mentioned above, is checked the TDP-N contact.To carry out if there is at least one to trigger TDP-N, then check the calling interval (level 502) in the network.This checks of great use for some IN agreement, and for example CS-1 and CS-2 are because its purpose is to avoid the SCP overload.When checking, promptly when not thinking the SCP overload, as mentioned above, carry out continuation at level 408 TDP-N of place by this.When calling interval by by the time, whether disconnect about the calling in this position at level 504 places and check.If no, then TDP-N carries out from level 406 continuation.When calling interval stoped the startup of business procedure, then the notice of functional definition can provide to the user thus.
Fig. 5 b provides the TDP-R of this second embodiment to carry out 130.At level 418 places, the contact first embodiment of the present invention as mentioned above, is checked the TDP-R contact.If there is the TDP-R of at least one triggering to carry out, then check the calling interval (level 512) in the network.When this check by by the time, promptly when not thinking the SCP overload, according to the present invention described above order continues TDP-R and carries out at level 420 places.When calling interval by by the time, whether disconnect about the calling in this position at level 514 places and check.If no, then TDP-R carries out from level 418 continuation.Can provide notice to the user about calling interval.
In the third embodiment of the present invention, the priority of business procedure is based on the controllability classification of distributing to them.In this embodiment, the controllability classification is distributed to business procedure, as shown in Figure 3, at this, controllability classification C1 distributes to business procedure SLP1, and C2 distributes to SLP2, and C3 distributes to SLP3.According to the present invention, when meeting with EDP-R and/or TDP-R, utilize the controllability classification of being distributed.Therefore, different controllability classifications are represented different priority by correspondence, and start business procedure according to the order of priority.For example, if C1 is corresponding with highest priority, C2 is corresponding with next limit priority, and C3 is corresponding with lowest priority, the execution sequence of these business procedure will be: SLP1, SLP2, and SLP3, no matter in the classification of related service test point, promptly EDP-R or TDP-R inner they when connect.In addition, carry out an inspection about the startup of the business procedure that whether allows to have a controllability classification of having distributed when meeting with TDP-R, that is, this controllability classification in question has not by another business procedure just in use.If allow to start, then start this business procedure and as waiting for instruction as described in saying.Otherwise, abandon this business procedure, and continue the execution of the TDP-R of another one TDP-R.Relevant reception instruction, SSP checks that they are whether in the controllability classification inside of business procedure.If no, ignore instruction and continue the execution of the EDP-R or the TDP-R of next business procedure then.Otherwise, get in touch the first above-mentioned embodiment, check instruction.
In the time can not starting business procedure or SCP connection failure according to the present invention, can continue the execution of next business procedure, can abandon test point, perhaps may need to disconnect and call out.For example, can be with the formal definition operation in this case of IN business information.
According to the present invention, when must be according to specific sequence starting execution sequence advantageous particularly during some business procedure at least.Usually, combinations of services provides different results according to the execution sequence of business.Sometimes, call out elementary in begin a business procedure or even impossible.The example of combination is can be near professional (accessibility service) and some Location Dependent Services (location dependent service), therefore therefore, can at first be performed and need have higher priority than Location Dependent Service near service needed.
The present invention also is suitable for using together with the business that realizes according to several different agreements.According to invention, when business procedure given behind the limit priority, at first start it then.After that, for example, under the help of the controllability classification of having distributed, can abandon other schemes of identical business.The priority of business procedure can also depend on customer location.The example of this kind function is to utilize having the professional of high priority and utilize the network being visited of CAMEL (custom program that is used for mobile enhanced logic) agreement to have the identical business of high priority in home network of CS-2 agreement.
Accompanying drawing relevant with them and explanation only are to be intended to illustrate thought of the present invention.The method according to this invention about its details, can change within the scope of claim definition.Though the present invention who mainly describes according to the specific category of related service test point in the above, this method can also be used with other distribution of related service test point.Aforesaid business procedure can be based on the business of exchange, the IN business, perhaps be similar to the professional business that still between control program grouping and control crosspoint, has the interface except the IN interface of IN, for example portable database of special number or call name database.When the different agreement that uses such as CorelNAP or CAMEL, even when connecting the control point, in identical BCSM, also can use the present invention, in the method according to the invention, also can transmit by relayed information relevant for other operations except that above-mentioned operation and the other times except that test point, for example relevant for the spontaneous message of up-to-date science and technology such as call release (ReleaseCall) or cancellation.
